Hi All,
Trying to figure out the way to create a vector of values inside a loop
I have a matrix pop:
Id yloc xloc weight
1
2
.
and spatial grid grid.dens with "coordinates" (x=xloc,y=yloc)
I want to create two more vectors: Food and Consumed inside the loop and
add those to pop so:
Id yloc xloc weight Food Consumed
1
2
.
I'm trying something like this but not getting what I want.
nagent=100
Food=list()
Consumed=list()
ind=function(pop, grid.dens){
for (i in 1:nagent){
Food[[i]]=grid.dens[pop$yloc[i],pop$xloc[i]]
Consumed[[i]]=pop$weight[i]*0.8*(Food[[i]]/(0.2+Food[[i]]))
Food[[i]]=Food[[i]]-Consumed[[i]]
}
Any thoughts?
THANKS!!!
Nico
